Definitions

• the present invention relates to cosmetic or dermatological dermatological preparations containing active ingredients for the care and protection of the skin, in particular the sensitive skin as well as especially in the foreground standing by intrinsic and / or extrinsic factors aged or aging skin and the use of such agents and Combinations of such active ingredients in the field of cosmetic and dermatological skin care.
• Cosmetic skincare is primarily understood as strengthening or restoring the skin's natural function as a barrier against environmental influences (e.g., dirt, chemicals, microorganisms) and against the loss of endogenous substances (e.g., water, natural fats, electrolytes).
• environmental influences e.g., dirt, chemicals, microorganisms
• endogenous substances e.g., water, natural fats, electrolytes
• the aim of skin care is also to compensate for the daily loss of fat and water loss of the skin. This is especially important when the natural regeneration capacity is insufficient.
• skin care products to protect against environmental influences, especially from the sun and wind, and delay the aging of the skin.
• the present invention relates in particular to products for the care of naturally aged skin, as well as the phenomena listed under a), e) and g).
• Products for the care of relaxed, especially aged, skin are known per se. They contain e.g. Retinoids (vitamin A acid and / or derivatives thereof) or vitamin A and / or its derivatives. Their effect on the structural damage, however, is limited in scope. In addition, there are significant difficulties in product development in stabilizing the active ingredients sufficiently against oxidative degradation. In addition, the use of vitamin A acid-containing products often causes severe erythematous skin irritation. Retinoids can therefore only be used in low concentrations.
• the accompanying skin is also associated with obesity and / or its associated cellulite.
• Cellulite - a widespread phenomenon - occupies a central position.
• the visible picture of cellulite is due to an increase in fat deposits in the subcutis (subcutaneous fatty tissue), a connective tissue weakness and a reduction in the flow conditions in the blood and lymph channels.
• the cause is thus a partial plant-related weakening of the connective tissue with simultaneous occurrence of enlarged fatty cell chambers as a result of obesity, unbalanced diet, lack of exercise.
• the development of cellulite can also be attributed to an increased permeability of the capillary walls, which allows the penetration of water into the connective tissue.
• the object of the present invention was therefore to find ways that avoid the disadvantages of the prior art.

• Cosmetic preparations with coenzyme Q10 are furthermore known from DE-A-33 09 850, which is used for the treatment of skin diseases, for the prevention of dystrophic and dysmetabolic skin conditions and for use in chemical and physical respiratory damage or in delayed respiration associated with aging and wear are suitable.
